Yes.
However it has not been established that the fit of the piston to liner is the problem. Is compression leaking down significantly when the engine is cold and turned over slowly?
It should hold compression and ''push'' ther piston down as you take it over tdc.
As Mr Davis says in his printed instructions, his conversion head will not perform with a worn engine.
I’m looking now at a bit over 2 hrs. run time between glow and diesel is it possible that it's just not broken in enough yet? It does not seem to have as much compression as my Enya 11 I’m determined to figure this thing out, I built this plane around this engine and all the research I did before making this engine choice told me that it would be a good match for this plane. In fact I’m pretty sure that Enya would fly it.
